Description
Technical field:
This utility model relates to analytical test sampling equipment technical field, a kind of liquid sampler.
Background technology:
At present, the analytical sampling of liquid is that glass tubing is directly goed deep into fill or barreled by the glass tubing with a both ends open
In liquid, pinning upper orifice with finger, extract out in bucket, the fluid sample taken out loaded in sample bottle in pipe, its shortcoming is
Inconvenience, incessantly, pipe is outer the most easily hangs liquid to liquid in pipe sample envelope, from probe tube to transfer in sample bottle time, be easily sprinkled upon filling
On outer or ground, being not easy to contamination control of storing in a warehouse, meanwhile, the sample volume every time obtained is limited, need to improve.
Utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, the liquid of convenient sampling
Sampler.
This utility model solves the scheme of described technical problem: a kind of liquid sampler, including the switch being sequentially connected with
Duan Guanti, middle linkage section body and sampling head section body, described switch segments body upper end is provided with controlled valve and lower end outer wall
Being provided with external screw thread one, described middle linkage section body upper end inwall is provided with female thread one and lower end outer wall is provided with external screw thread two,
Described sampling head section body upper end inwall is provided with female thread two, and described external screw thread one couples with female thread one, described external screw thread two
Coupling with female thread two, described switch segments body, middle linkage section body, the inner and outer wall of sampling head section body are equipped with poly-
Tetrafluoroethene anti-stick coating.
The length of described female thread one is more than the length of external screw thread one, and the length of described female thread two is more than external screw thread two
Length.
Described switch segments body, middle linkage section body, the outer wall of sampling head section body are equipped with scale.
Described controlled valve is ball valve.
Prominent effect of the present utility model is: liquid sampler includes the switch segments body being sequentially connected with, middle linkage section
Body and sampling head section body, can select the middle linkage section pipe of different length according to liquid depth and required sampling amount
Body assembles, it is also possible to is threadedly coupled together the various different lengths of composition with multiple middle linkage section bodys head and the tail and makes
With, convenient and practical, and use thread connection, easy accessibility between switch segments body, middle linkage section body, sampling head section body
And good seal, switch segments body, middle linkage section body, the inner and outer wall of sampling head section body are equipped with politef to be prevented
Adhesive coating layer so that during sampling, liquid will not form extension liquid and unrestrained outside pollutes at the inside and outside wall of body, and controlled valve is
Ball valve then ensures good airproof performance, and during sampling, liquid will not trickle down outside.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is described in further detail.
As it is shown in figure 1, a kind of technical scheme of this utility model offer: a kind of liquid sampler, including opening of being sequentially connected with
Close section body 1, middle linkage section body 2 and sampling head section body 3, described switch segments body 1 upper end be provided with controlled valve 12 and
Lower end outer wall is provided with external screw thread 1, and described middle linkage section body 2 upper end inwall is provided with female thread 1 and lower end outer wall
Being provided with external screw thread 2 22, described sampling head section body 3 upper end inwall is provided with female thread 2 31, described external screw thread 1 and female thread
One 21 couple, and described external screw thread 2 22 couples with female thread 2 31, described switch segments body 1, middle linkage section body 2, sampling
The inner and outer wall of head section body 3 is equipped with politef anti-stick coating.
The length of described female thread 1 is more than outer spiral shell more than the length of external screw thread 1, the length of described female thread 2 31
The length of stricture of vagina 2 22.
Described switch segments body 1, middle linkage section body 2, the outer wall of sampling head section body 3 are equipped with scale.
Described controlled valve 12 is ball valve.
When in use, liquid sampler includes the switch segments body 1 being sequentially connected with, middle linkage section to this utility model
Body 2 and sampling head section body 3, can select the middle linkage section of different length according to liquid depth and required sampling amount
Body 2 assembles, it is also possible to be threadedly coupled together the various different lengths of composition with multiple middle linkage section bodys 2 head and the tail
Use, convenient and practical, insert liquid after assembling liquid sampler and open controlled valve 12, owing to pressure difference liquid is pressed into
In liquid sampler, reach required sampling amount closing switch valve 12 and vertically take out liquid sampler, then open controlled valve
Sample in liquid sampler can be poured in sampling bottle by 12, switch segments body 1, middle linkage section body 2, sampling head section pipe
Thread connection, easy accessibility and good seal, switch segments body 1, middle linkage section body 2, sampling head section body is used between body 3
The inner and outer wall of 3 is equipped with politef anti-stick coating so that during sampling, liquid will not form extension at the inside and outside wall of body
Liquid and unrestrained outside pollutes, controlled valve 12 then ensures good airproof performance for ball valve, outside during sampling, liquid will not be trickled down.
Finally, embodiment of above is merely to illustrate this utility model, and is not limitation of the utility model, relevant skill
The those of ordinary skill in art field, in the case of without departing from spirit and scope of the present utility model, it is also possible to make various change
Changing and modification, the technical scheme of the most all equivalents falls within category of the present utility model, patent protection model of the present utility model
Enclose and should be defined by the claims.
